may be consi ered thatthehook-shaped ;members of'the drill steelholder Iprojectupwardly'from the base-of the ho der. evident, however, that it is notnecessary for It is f this holder to be in a vertical positionor in such position that its" base is lowermost.

This position, however, is assumed in the brief description of the figures and this assumption will be continued throughout the description unless otherwise stated.

Let the numeral-5 designate the drill steel which as shown'in the drawingis of the o'rdinary hexagonalconstruction in-c'ross section;

This steel is provided with a central longitudinal opening 6 open atthe forward orcutting' extremity of the drill and closedat its rear extremity. Intermediatethe extremities vofthe opening 6, the, drill is provided with a transverse orifice 7 1 communicating with the central opening. At the outer extremity of the transverse opening 7, the drill steel is recessed as shown-at 8 to receive the outer'ex sembled inoperatiye relation with the water tudinal opening 17 of this nozzle registerswith the orifice 7 of the drill steel when the nozzle is screwed to position as shown in Figs. 1 and 3. A look nut 18 is mounted upon the threaded portion of the nozzle and may be screwed upwardly against the base of the drill steel holder after the'nozzle hasbeen screwed inwardly to its limit of movement (see Figs. 1 and 3).

The upper portions of the hook-shaped members 14 of' the drill steel holder, are shaped to fit thedrill steel or rather to fit two of the six sides thereof, namely the uppermost side A and one of the adjacent inc ined sides B of the hexagonal tool (see Figs. 3 and 4). As these hook-shaped members project over the drill steel in opposite directions, it is evident that when the nozzle is screwed. to position whereby both hookshaped members are brought into such relation with the drill steel that the latter fits the counterpart faces of both of said members, the steel is locked securely in lace against movement in any direction. or convenience of manipulation, the nozzle is provided with a collar 19 adapted to receive a wrench.

From the foregoing description the use of our improved water attachment for drills will be readily understood. In attaching the drill steel, it maybe placed in positionb'etween the two hook-shaped members 14 as shown in Fig. 5. It isthen given a"; quarter turn whereby it is brought into position restin on the upper surface of the base 13 and .be ow the hooks 15 of the members 14. The nozzle may then be screwed into the opening in the base of the holder whereby its outer rounded extremity is caused to engage the recess .8 of the drill steel into which it fits closely causing its passage 17 to register with the lateral orifice 7 of the drill. When this occurs the drill steel is caused to fit the faces A and B of each of the hook-shaped members thus locking the drill steel securely in place. The nozzle must be connected with a suitable conduit for supplying water to the drill steel. As the rear extremity of the longitudinal opening 6 of the drill steel is closed, the water introduced must pass out at the forward or cutting extremity of the drill whereby the rock cuttings are washed from the drill hole.v

Having thus described our invention, what we claim is:

1. In a water attachment for drills; the combination with a drill steel having a longitudinal opening and a transverse orifice communicatingfwith the opening, of a holder comprising hook-sh aped extremities projecting in opposite directions adapted to recommunicating wit ceive and support the drill steel, and a nozzle screwed into a threaded opening formed in the holder, whereby its passage is caused to register with the transverse orifice of the drill, the said nozzle being threaded in the holder and made to engage the dIlll steel whereby the latter is locked in the holder, substantially as described.

2. A drill steel holdercomprismg a base and two members projecting outwardly from the base and having hook-shaped extremities projecting over the drill steel in opposite directions, the base of the holder having a threaded opening, and a nozzle adapted to be screwed into said opening, substantially as described.

3. A water attachment for rock drills,

comprising a holder composed of a base having a threaded opening and two outwardly projecting members having hooks projecting n opposite directions,-the said members being separated to receive the drill steel when occupying positions at right angles to its position when assembled in operative relation with the holder, and a nozzle screwed into the opening formed in the base of theholder,?substant1ally as described.

4. Ina water attachment for rock drills, the combination with the drill steel having a central longitudinal passage 0 on at the forward or cuttin extremity o the steel, its rear extremity eing closed, the steel having a transverse orifice communicating with the longitudinal opening, and a drill steel holder comprising a base having a threaded openin and two outwardly pro ecting hook-shape members the base, eir hook-shaped extremities projecting over thedrill steel in opposite dlrec- 'tions, and a nozzle screwed into the opening in the base of the holder and arranged to engage thedrill steel whereby its passage is caused to register with the transverse orifice of thedrill steel, substantiallyas described:
